Question about 2008 Chevrolet Trailblazer

1 Answer

'08 Trailblazer low tire indicator light comes on when weather is cold.Tire pressures are all the same and at the recommended psi. Now the StabiliTrack warning light and the StabiliTrack service light is on too. What the heck? There is 46,000 miles and we bought used but is a GM certified car so warantee is extended to 48,000. It is the inline 6 cyl if that info is needed.

00Linc ls tires P235-50R -17 running 40PSI LABEL IN DOOR SPEC 30PSI . Would like to no what to do don't want to damage tire.


because it is a low profile tire with a wide tread , the 30 psi is a recommended pressure for a standard size tire
however at 30 psi you will probably find that it will wear with an under inflated wear pattern and the 40 psi is used to sit the tread flat on the road
best talk with a good tire shop as they have experience and reports form a vast range of customers who talk about the pressures they run to get the best wear from the tires
the tires I run are standard and the recommended pressure is 32 psi but the make of tire actually runs best on 38 psi and that comes from the tire manufacturer

2005 grand Cherokee service tire pressure system


I found this on another site, it may help to understand what is happening, I also saw that there is a problem with the valve stems cracking since they're made out of aluminum and causing that problem. Here's the explanation provided on another site:

RodneyJ Answered 6 years ago
If a customer with a 2005 or later DaimlerChrysler vehicle equipped with Tire Pressure Monitoring (TPM) is concerned that the TPM lamp is on continuously, please be sure to inform the customer that the system is in place to warn of a low tire pressure situation, and a system diagnosis may not be required. The customer should be aware of the following: The Tire Pressure Monitoring (TPM) System will warn the driver of a low tire pressure based on the vehicle recommended cold placard pressure (the placard is located on the drivers side B-pillar).
The tire pressure will vary with temperature by about 6.9 kPa (1 psi) for every 6.5 Degrees C (12 Degrees F). This means that when the outside temperature decreases, the tire pressure will decrease - the customer should adjust his tire pressure for this decrease in pressure - please refer the customer to his vehicle owner's manual for information on how to properly inflate his vehicle's tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure.
The TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature effects.
The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recommended cold placard pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold placard pressure in order for the TPM warning lamp to be turned off. The system will automatically update and the TPM warning lamp will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 25 kph (15 mph) to receive this information.


FOR EXAMPLE:

A 2006 300 has a recommended cold (parked for more than 3 hours) placard of 207 kPa (30 psi).

If the ambient temperature is 18 Degrees C (65 Degrees F) and the measured tire pressure is 186 kPa (27 psi) the TPM lamp will be OFF.

IF NOTHING IS DONE TO THE AIR PRESSURE IN THE TIRES and the ambient temperature drops to 20 Degrees F (-7 Degrees C) while the vehicle is parked, the approximate tire pressure will be 157 kPa (23 psi) and the TPM lamp will be ON.

IF THE VEHICLE IS DRIVEN TO REACH NORMAL OPERATING TEMPERATURE

WITHOUT ADJUSTING THE AIR PRESSURE and the ambient temperature stays at -7 Degrees C (20 Degrees F), the approximate tire pressure will rise to 186 kPa (27 psi) and the 1PM lamp will be ON.

To turn the TPM lamp OFF the tires must be inflated to the vehicle recommended cold placard pressure.

In order to properly maintain vehicle tire pressure, please refer to the owner's manual for additional information regarding tire inflation.

NOTE :Tire pressure should always be set based on cold inflation tire pressure (defined as the tire pressure after a vehicle has not been driven for more than 3 hours - and in outside ambient temperature).

Seasonal temperature changes will affect tire pressure, and the TPM system will monitor the actual tire pressure in the tire.
If a diagnosis of the system is required (for example, the lamp did not extinguish, or the lamp is flashing), please refer to service information available in TechCONNECT for additional information for TPM diagnosis. Please be aware that if the Wireless Control Module (WCM) is replaced, the TPM placard values may need to be reprogrammed. The TPM placard values do NOT need to be updated if the WCM has NOT been replaced, the TPM placard values are properly set at the factory.

Air pressure in the tires drops when it is cold (as much a 5 PSI), as you drive they heat up and that makes them fall within the correct pressure limits to turn off the low tire pressure warning. I suggest you get an accurate tire gauge and air your tires up to 32 PSI all around.

At what tire pressure is the tire pressure warning indicator activated


The LOW TIRE PRESSURE warning light will come on when the pressure is 25% below the manufacturer's recommended pressure. If I recall correctly, the 2007 Sonata has a manufacturer's recommended tire pressure of 30 psi. There is a tire label (sticker) on the inside driver's door jamb ('B' Pillar which tells you what the manufacturer's recommend tire inflation pressure should be. Once you have that value, you can calculate 25% of that & find the pressure at which the warning light should come on. NOTE: The TPMS (Tire Pressure Monitoring System) does not continually nor constantly scan the sensors in the wheels for this information - once every 3 to 10 minutes.

2000 Sienna exclamation light on dash


That usually means that one or more of your tires has dropped below the level of air pressure that the manufacturer recommends. It is basically a low pressure warning light. This way you will know to find a place to check your tire pressures. Look on your tires sidewall and you will find a cold psi rating and a hot or warm psi rating. The tire pressures need to stay within those parameters in order for the light to not come on. As the tire warms from motion the air inside begins to expand and will read a higher pressure than if the tire is cold. Check your pressures and if any of the tires have a low pressure (below 30 psi) it should be inspected...........Or you may be leaving your emergency brake on. Pull up then push down to release a hand break lever and push all the way down and pull hard on the release lever for a foot brake. Another possibility is the car needs brake pads soon.

If this is right, is the Tire Pressure Monitor Sensor (TPMS) o Tire Pressure Monitor Systems (TPMS) are being used on more and more new vehicles. Low tires are potentially dangerous, especially if a vehicle is heavily loaded and traveling at highway speeds during hot weather. A low tire under these conditions is a blowout waiting to happen. The inflation pressure of the tires should be checked regularly, but many motorist do not check their tires. That is why Tire Pressure Monitor Systems are coming into use.

Tires are designed to operate within a certain pressure range. The recommended inflation pressure can usually be found in the vehicle owner's manual and on a decal that may be located in the glove box or door jam. The recommended inflation pressure is designed to give the best combination of ride comfort, load carrying capacity and rolling resistance.


NOTE: The maximum cold inflation pressure on the sidewall of a tire is NOT the recommended inflation pressure. It is a maximum limit for the tire only. The recommended inflation pressure for most passenger car tires is 32 to 34 psi (cold).

Hope helps (rated this).

There is a light on the dash that looks like a horseshoe with an exclamation point inside...didn't get a manual....what does this icon mean


I believe this is a low tire pressure indication.
This is supposed to be a tire with an exclamation.
A 5-10 psi drop could set this off.

Toyota 2007 corolla dashboard icon shows symbol like horseshoe eith exlamation point in it


Sounds like the low tire pressure indicator. Check your tire pressure is correct in all four tires. This happens when the tempature outside starts to drop and so does the pressure in the tires. The recommended tire pressure should be listed on the inside of the driver's side door. Most tires are 32 psi cold. After the tires have been filled to proper pressure it may take 15 minutes for the light to shut off.
